Method
A soundproofing process shaped by diagnosis, material logic, and installation discipline.
01
Diagnose the noise path
We identify whether the problem is airborne sound, impact vibration, flanking transmission, weak doors, glazing, or reverberation.
02
Specify the right assembly
We recommend build-ups based on the room, use case, finish expectations, and disruption tolerance rather than generic products.
03
Install with material discipline
Precision detailing matters. Sealing, decoupling, mass, isolation, and finishing are handled as one acoustic system.
04
Deliver calm, measurable comfort
The result is a quieter interior that feels intentional, private, and more comfortable to inhabit every day.
What gets specified
Each intervention is assembled to control transmission, vibration, leakage, and internal harshness together.
Acoustic wall systems and decoupled linings
High-performance door seals, cores, and thresholds
Secondary glazing and insulated window strategies
Floating floors and impact-noise reduction layers
Ceiling isolation systems and service penetrations sealing
Reverberation control with architectural acoustic finishes
Project settings
Designed for spaces where comfort, discretion, and clarity matter.
01
Urban homes

Plymouth apartment living room
Plymouth, Devon
Challenge
A city apartment was affected by inter-flat television spill, corridor activity, and impact noise from the flat above, especially in the evening.
Solution
Ceiling isolation improvements, junction sealing, selective wall treatment, and door-set detailing improved separation from neighbouring flats.
Acoustic performance
Before64 dB from inter-flat transfer and impact-related peaks
After46 dB after isolation and sealing improvements
18 dB reduction in apartment-noise intrusion
Client outcomes
Calmer eveningsLess overhead disturbanceMore comfortable everyday living

Client perspective
Spaces that feel intentional and perform measurably.
"The room felt quieter immediately, but what stood out most was how intentional the finish looked. Nothing about the solution felt improvised."

Questions
Common concerns about acoustic performance and integration.
Can you help even if I do not know where the noise is coming from?
Yes. Many problems involve more than one transmission path. Terbium begins by diagnosing how sound is actually entering or escaping the space before recommending treatments.
Do premium finishes still work with soundproofing systems?
They can. The company approach is to integrate acoustic performance with interior quality, using hidden layers, tailored panels, and finish-sensitive detailing.
Is soundproofing the same as acoustic treatment?
No. Soundproofing focuses on reducing transmission between spaces, while acoustic treatment improves how a room sounds internally. Many projects benefit from both.
Start the conversation
Bring a quieter, more private atmosphere to the rooms that matter most.
Share the type of space, the source of the disturbance, and what better performance would mean for the people using it. Terbium Soundproofing can then recommend the next best step.

Service coverage
Focused on Devon's major towns, cities, commuter corridors, and high-noise neighbourhoods.
We are focusing on Devon rather than broad regional coverage, with priority areas including Exeter, Plymouth and Devonport, Torbay, Exmouth and East Devon, North Devon market towns, and settlements where roads, rail lines, dense housing, flats, and major workplaces create repeat acoustic challenges.
